The Barn project, a geospatial data grid prototype, provides a grid environment for applications of the nationwide geological survey data. Barn is developed based on the Globus Toolkit. Through web portal, users can manage the grid resources, perform browsing, querying and analysis against the spatial data. According geospatial application nodes are organized into application domains. The node management in Barn system consists of four modules: resource management, domain management, index service and web portal. Addressing the system requirements such as achieving node autonomy and avoiding a single point of failure, we deploy multiple domain servers and multiple index servers. This will increase scalability and flexibility of the system.
